Once a bustling hub for farming and business in southern Gwinnett, the Yellow River Post Office Site is now a 5-acre passive park featuring a unique assemblage of historic structures, including the original post office building and the 1840s Hudson-Nash House, which was moved from across the street in 2021. The two-story Plantation Plain farmhouse was built by Thomas Hudson, who played a leading role in the community.

After establishing a 562-acre plantation along the Yellow River, he ran a general store and post office, worked as a county surveyor, and served as an elected State Representative for Gwinnett. Following the Civil War and Reconstruction, the property was sold to Lewis Nash in 1876 and then to his cousin William Thomas Nash in 1880. It remained in the family for over a century.

Visitors can tour the farmstead grounds on a short loop with interpretive signs chronicling history along the way, and a scattering of picnic tables to relax and enjoy the scenery.
